  2. 11. Large Eddy Simulation of Atomizing Sprays

    Author : Holger Grosshans; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomization; Multiphase Flows; Jets; Sprays; Large Eddy Simulation;

    Abstract : Liquid-gas two-phase flows occur frequently in daily life, in nature e.g. falling rain drops or waves in the sea, and in industrial applications, e.g. READ MORE

  4. 12. Melt-water interactions in a reactor containment : from integrated assesment to phenomenological studies

    Author : Timo Okkonen; KTH; []
    Keywords : ;

    Abstract : This thesis examines melt-water interactions for theex-vessel phase of a severe reactor accident. The studies startfrom the development of an assessment methodology that tiestogether the vessel melt release scenarios and the mainprocesses affecting the melt-water interaction effects in thereactor containment.

  5. 13. A study of some aspects of gas-slag-metal interactions : Towards dynamic process model and control

    Author : Mattias Ek; Sichen Du; Stuart Millman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; process modeling; phosphorous capacity; penetration depth; slag foaming; mixing time; inclusion removal;

    Abstract : The present thesis deals with the development of a new type of dynamic model for metallurgical reactors. It also covers some of the theoretical aspects of steelmaking that is necessary to include in such an application. The thesis consists of modeling work, high temperature experiments and cold model experiments. READ MORE

  6. 14. The One-Dimensional Turbulence Model Applied to Spray Atomization

    Author : Amirreza Movaghar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Primary breakup; Turbulence; One Dimensional Turbulence ODT ;

    Abstract : Numerical simulation of the spray behavior is an important part of engine research and is critical for combustion optimization. Successful implementation of the advanced modeling tools for sprays is strongly dependent on our current understanding of the physical processes involved. READ MORE

  7. 15. A study of bubble behaviors in a liquid steel bath

    Author : Yonggui Xu; Mikael Ersson; Pär Jönsson; Dongyuan Sheng; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The fundamental aspects of rising argon bubbles in molten metal flow were investigated by numerical simulations. The process of a bubble rising in the molten metal includes two steps, one is the bubble rising inside the liquid, and the other one is the bubble rising across the liquid surface. READ MORE
